BOILER SETTING AND SUPPORT.

SPECIFICATION forming part of Letters Patent No. 686,787, dated November19, 1901. Application filed March 6, 1901. Serial No. 50,023. (N0model.)

To a/ZZ whom it rotary concern:

Beit known that I, HARRY LEE VAN ZILE, a citizen of the Unit-ed Statesof America, and a resident of the city, county, and State of New York,have invented certain new and useful Improvements in Boiler Settings andSupports, of which the following is a specification.

My invention relates to improvements in boiler settings and supports,and it is especially applicable to the type ofboiler known as thewater-tube type.

The objects of my invention are to produce a boiler-setting which shallbe simple and effective in its construction and operation and oneespecially convenient for erection and also one that may be readilyadapted either for manual or mechanical stoking.

My invention consists in securing to the front of the steam-drum a shortlug which has a pivotal support resting upon a transverse girder, thesaid girder, which at the same time forms part of the boiler-front,being secured at its ends to vertical columns forming part of the framefor the boiler-front in such a way that the said transverse girderintermediate of its ends is independent of those portions of theboiler-front which are beneath it, in supporting the tube cleaning doorsupon transverse girders, in covering the tirefront below the tube-cleaning doors with a series of plates, each plate containing afiringdoor and an ash-pit door for manual tiring, and in so securingsaid plates in position that they may be readily removed for theinstallation of mechanical stokers, leaving a clear space the entirewidth of the furnace, and in other novel features of construction to behereinafter more fully pointed out and described.

In the drawings accompanying and forming part of this specification,Figure 1 represents a vertical longitudinal section showing a boilersupported by my improved boilersetting. Fig. 2 represents a front viewof the same. Fig. 3 represents a partial transverse section, on anenlarged scale, on line B B, Fig. 2. Fig. 4 represents a partialtransverse section on line A A, Fig. 2. Y

Reference characters are used in the same sense in all of the drawingsand the specification.

Numeral 1 represents the cylindrical shell of a water-tube boiler.

2 represents the front and 3 the rear waterleg.

4 represents the water-tubes connecting the front and rear water-legs.

5 represents a bracket secured to the front head 6 of the drum 1 bybolts or rivets. This bracket is provided with the lower transverseflange 7, having the concave cylindrical recess 8.

9 represents a bearing-plate adapted to rest on the girder 11. Thisplate is provided with the concave cylindrical recess 10, and I preferto form the girder of two channel-bars, as shown, separated by a shortspace for receiving the tongue 12 of the bearing-plate 9. Between therecesses 8 and 10 is a cylindrical pin 25, adapted to fit said recesses.This pin 25 may be formed integrally with the bracket 5 of thebearing-plate 9. Y

The rear of the boiler is supported by the rear wall13, on which thereis a bearing-plate 14, the shoe 15 being placed under the bottom of therear water-leg and a roller 16 being placed between the said shoe andsaid bearing-plate.

The girder 11 is supported at its ends upon vertical columns 16. Securedto said columns are two transverse girders 17 and 18, preferably made ofchannel-bars, and which girders are independent of the girder 11.Secured to the girders 17 and 18 is the frame 31 for the tlue-cleaningdoors 19. Between the lower flange of the frame 31 and girder 1S isformed the recess 32, which receives the upper ends of the plates 20. Inthe plates 2O are mounted the frames for the tire-doors 21 and theashpit doors 22.

23 represents the jamb, which is supported by the short columns 24,which support the brick arch 26.

27 represents the bridge-wall which divides the tiring-chamber 28 fromthe combustionchamber 29. The floor 30 of the combustionchamber isformed of any suitable material, preferably brick, and inclines upwardlyfrom the rear wall to the upper portion of the bridgewall 27, therebygiving substantial support to the bridge-wall, which, as heretoforeconstructed, is frequently knocked out of place by being rammed with'the bars used to clean IOO the grate. It Will be seen that by means ofthis construction the boiler may be pitched at various angles Without inany Way affecting its front support. The bracket 5 is relatively narrow,and the rollers 16 are located some distance apart, so that the boileris practically supported by three points, thereby avoiding any unduestrains due to unequal expansion or contraction and greatly facilitatingthe erection of the boiler. It is also seen that the support for theluefcleaning doors 19 is independent of the girder 11 and that the framefor said doors, which is usually made of cast-iron, is not likely to becracked or injured, as might happen if there were a connection betweenthe girder 11 and the girder 17, supporting the flue-cleaning doors. Itis also seen that the plates 20, which carry the firing-doors 2l andash-pit doors 22, may be easily removed without disturbing theflue-cleaning doors or the boilersupport in case it is desired toinstalla mechanical Stoker.

Having thus described my invention, what I claim is- 1. Inaboiler-supp0rt,the combination with the boiler-shell of a bracketsecured to the front head of said shell, a transverse girder locatedbeneath said bracket and a pivotal connection between said girder andsaid bracket.

2. In a boilersupport,the combination With the boiler-shell, of abrackethaving a concave recess in its lower side, a girder located beneath saidbracket, a bearing-plate on said gir-der, having a concave recess in itsupper side, and a cylindrical pin engaging the concave recesses in saidbracket and said bearing-plate.

3. In a boiler-support for Water-tube boilers, having front and rearWater-legs connected by a steam-drum, the combination with aroller-bearing under saidA rear Waterleg of a bracket secured to thefront head of said steam-drum, and a transverse girder located beneathsaid bracket.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

HARRY LEE VAN ZILE.
